Basics
For all tests make sure that:
Metal Ground
This test verifies proper operation of your monitor on metal ground monitoring as
well as EMI detection.

Setup switches allow you to set the parameters in accordance to your specification.
Metal ground impedance setting is done using dip switches 5...8.

Pressing a “Fail” push-button switch will result in resistance that is 1 Ohm
higher than set above, pressing the “Pass” push-button switch will result in
resistance that is 1 Ohm less. For example, if your factory is using 10 Ohms as
specification for ground impedance, then the monitor set to 10 Ohms should
pass at 9 Ohms and fail at 11 Ohms.

Places of contact for metal grounds test for WS Aware and Ground
Master monitors. In other monitors it may vary. In all cases disconnect
monitor from monitored tool and bench grounds for the test.

The checker provides high frequency signal to test EMI detection threshold. EMI
level is set using dip switch 9 9 9 9 9 . The checker provides two different levels of high
frequency signal -- “elevated” and “normal.” In position 1 the EMI level is
“elevated,” in position 0 the level is “normal.” Pressing “High” push button
switch will result in high signal level within its range, pressing “Low” push
button will result in low signal within its range. Note that internal EMI generator
drive may be insufficient to drive extremely low load, such as 0 or 1 Ohm.
